Load Dependent Critical Speed
(Texas A&M University. Turbomachinery Laboratories, 2010)
Verification Full Load Test Of 900 T/H (1,980,000 LB/H) Large Mechanical Drive Steam Turbine For ASU Up To 200 MW (268,000 HP) Based On Principle Of High Scale Model Similarity.
(Texas A&M University. Turbomachinery Laboratories, 2009)
In 2009, the authors designed a compressor drive steam turbine for air separation units (ASU) application up to 200 MW (268,000 hp), using large 500 mm (19.7 inch) blade rows, which have a low-pressure (LP) flow capacity ...
Centrifugal Compressor Applications - Upstream And Midstream.
(Texas A&M University. Turbomachinery Laboratories, 2009)
Centrifugal compressors are used in a large number of different compression application. This tutorial addresses applications for centrifugal compressors in the upstream and midstream sector, such as LNG compression, ...
The Effects Of Pulsations On The Surge Margin Of Centrifugal Compressors In Stations With Both Reciprocating And Centrifugal Compressors.
(Texas A&M University. Turbomachinery Laboratories, 2009)
Mixed operation with both centrifugal and reciprocating compressors in a compression plant poses significant operational challenges as pressure pulsations and machine mismatches lead to centrifugal compressors’ instabilities ...
Rotordynamic Stability Of A 9500 Psi Reinjection Centrifugal Compressor Equipped With A Hole Pattern Seal-Measurement Versus Prediction Taking Into Account The Operational Boundary Conditions.
(Texas A&M University. Turbomachinery Laboratories, 2009)
Extensive stability measurements were performed during the full-load, full-pressure factory testing of a five-stage inline centrifugal compressor. The compressor, tested up to a maximum discharge pressure of 655 bar (9,500 ...
Steam Turbine Pipe Strain Case Study
(Texas A&M University. Turbomachinery Laboratories, 2008)
This is a case study of a new steam turbine installation in which pipe strain became an issue after commissioning and start-up. This case study will bring light to the use of shaft indicator movement vs. turbine casing ...
Torsional Instability Of Cooling Tower Fan During Induction Motor Startup
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Torsional instability during starting of an induction motor has caused excessive torque oscillation and eventual failure of gearbox pinion teeth of a cooling tower fan train. A torsional instability appeared due to a steep ...
Double Flow Refrigeration Compressor Inlet Piping Design and Analysis
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Objective: • Design an inlet piping system for a double flow centrifugal compressor that effectively utilizes existing site spacing constraints: • Distributes flow to each inlet evenly with minimal pressure loss and without ...
Why Proper Low Pass Filter Settings on Crosshead Vibration Signals are Crucial to Minimize Risk of Missed Detects
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Crosshead guide acceleration measurements have gained mainstream acceptance by operators of API 618 recips and now joins frame velocity as a recommended shutdown parameter in the 5th edition of the API 670 Machinery ...
